A probe into prison extremism found that letting extremists mix with other lags was ‘potentially lethal’

The authorities are said to be desperate to prevent Choudary, 49, from brainwashing vulnerable inmates.

The decision on whether to keep him in a separate unit will be made by officers at the jail where he will be held – which is being kept secret.

But it is unthinkable that they will allow him to mix freely with other inmates.

One expert said: “He’s an extremely dangerous man.

“He’s far more dangerous here in our free United Kingdom than he would be with ISIS.”

Dad-of-five Choudary will be sentenced in September, when he is expected to get ten years behind bars.

'Attack mag'

Twitter bosses let Choudary post his backing for attacks on French magazine Charlie Hebdo four years before gunmen killed 12 staff.
Steve Stalinsky, of the Middle East Media Research Institute, which monitored him for years, said it was shameful the firm took no action at the time. Twitter has suspended 235,000 accounts for promoting ­terrorism in the past six months.
